Q1: 1/4 km = ____________ m
Ans: To find how  many m are there in a 1/4 Km kilometer
As we know that,
1Km = 1000m
Therefore, 1/4 Km = 1000/4 m
1/4 Km = 250 m
Hence, 250 m are there in 1/4 km.

Q2: 1/2 km = _________ m
Ans: To find how many m are there in a 1/2 Km kilometer
As we know that,
1 Km = 1000 m
Therefore,
1/2 km = 1000/2 m
1/2 = 500
Hence, 1/2 km = 500 m

Q3: Fill in the blanks 7750 m = _____ km _____ m ________cm
Ans: Since 7750 m = 7000 m + 700 m + 50 m
As we know that
1 km = 1000 m
$$\therefore 7000\ m = 7\ km$$
Also 1 m = 100 cm
∴ 50 m = 5000 cm
Therefore, 7750 m = 7 km + 700 m + 5000 cm

Q4: Fill in the blanks:
12 km = _____ m
Ans: 12Km = _____ m

800(1000)(100) + 250(100) + 45
80000000 + 25000 + 45
80025045cm
